Radiofrequency Perforation of an Atretic Pulmonary Valve with a Modified Coronary Wire and Electrocautery Pencil.

Radiofrequency (RF) perforation of an atretic pulmonary valve is commonly performed in patients with pulmonary atresia with intact ventricular septum with specifically designed RF wires. In difficult anatomy or low-resource centers, this may instead be successfully performed with a modified coronary guide wire and an electrocautery surgical pencil. [ABSTRACT FROM AUTHOR]
